1-androsterone + Thioridazine
Thioridazine brand name: Mellaril.
We found no known interaction between 1-androsterone and Thioridazine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
1-androsterone and Thioridazine
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Thioridazine and 1-androsterone in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Thioridazine
Interactions in our licensed database are recorded against drug classes, not just single drug names. Thioridazine is filed under 10 classifications — including phenothiazines, antipsychotic drugs, cytochrome p450 2c19 (cyp2c19) substrates. 1-androsterone has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Thioridazine’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Thioridazine page
“Thioridazine (Mellaril) is an older antipsychotic already known for disturbing the heart's rhythm, and the supplements that worry me most here do the same thing, stretching the QT interval further. Grapefruit in large amounts sits in that group, alongside ephedra and several other major-rated entries.”

About 1-androsterone
What is 1-androsterone?
- Muscle building
- Increasing strength
- Athletic performance
- Body recomposition
1-Androsterone (1-DHEA or 1-Andro) is a synthetic prohormone marketed to bodybuilders for muscle and strength gains, but it has not been proven safe or effective in quality human studies. It can affect hormones and may harm the liver and other organs, so most pharmacists would recommend avoiding it.
Synthetic compound (not a plant part) · Capsules, tablets, sometimes combined with other prohormones
An interaction check asks whether these two react with each other — it does not ask whether 1-androsterone is a good idea for someone in your situation. Here is what our 1-androsterone record says about it on its own.
1-androsterone: dosing
There is no established safe or standard dose for 1-androsterone, and no medical guideline supports its use. Products vary widely in strength and ingredients.Because of the health risks involved, the safest choice for most people is not to use it at all. Never combine it with other prohormones or hormone products.

About Thioridazine
What Is Thioridazine Used For?
Brand name: Mellaril
Thioridazine Hydrochloride tablets are used for the management of schizophrenia — but only in patients who have already tried at least two other antipsychotic medications without adequate results, either because those drugs didn't work well enough or caused intolerable side effects.
Because thioridazine carries serious heart-rhythm risks, it is considered a last-resort option for schizophrenia, not a first-line treatment. It is not approved for dementia-related psychosis or any other psychiatric condition.
